TQ @ZZ wwm "my @lwrm ing the spokes B not cut at and their ends 5o De it known that I, JOSEPH BREITENMOSER, fastened to the tires A, but bent, so as to form a c1tizen of the United States, residing in the the irregularly-shaped loop, as shown in Fig. city of St. Louis and State of Missouri, have 9, the closed end of this loop being fastened invented certain new and useful Improveto the tires A.

011 the line 2 2 in Fig. l. The forward end of the saddle-frame E is 45 The wheel proper consists in one or two supported on the projecting ends of the shaft outside tires A, to which the outer ends of II on the outside of the motor-wheels I, and the spokes B are attached. There are prefpivotally secured thereon by the head and nut erably two tires A set a short distance apart, on the ends of the bolt T, let through the holas shown in Figs. 2 and 9, and the wire formlow center of the shaft II. The back end of the sat'ldlc-frainc is supported by being secured to the loose rings l\'..

The loose rings K, there being one on each side of the wheel,are of a diameter somewhat smaller than that of the track-rings D and are situated just outside therings I). rlhey are secured together by the several connecting-rods ci,on which are mounted the frictionwheels l), one on either end of the rods, which run on the tracks and maintain the frame as a whole in a definite position laterally relative to the track-rings, but still allowing the movable rings to revolve within the trackrings independently thereof.

To the loose-rings I( are secured the downwardly and baekwardly projecting trailingarins L, into the ends of which are secured the small road-wheels l, which act in using the machine as steadying and steering wheels.

The handle-levers M are pivotally secured to the shaft Il just inside the motor-wheels I, and are connected at the top by the handleba-r ynl.

To the handle-levers at a point a convenient distance from the fulcrum-point at the shaft Il is pivotally secured the forward ratchet pawl N, which engages with the notches i in the periphery of the motor-wheels and operates them by the forward or pushing movement of the handle-levers M.

Attached to the handle-levers M at a point a convenient distance from the fulerum-point are the backwardly-extending pawl-bars O, the ends of which are in a position to engage and operate with the studs d on the trackrings in the backward or pulling movement of the handle-levers M. rlhere are )referably several holes o, formed in the handle-levers M as points of attachment i'oi' the ends of the pawl-bars O, so that the leverage effected thereby is adjustable.

The saddle or seat l is secured to the sadtile-supporting frame E in such a position that when a person occupies theseat sitting in a normal position the center oi gravity of his weight is directly below the center of the wheel.

To the loose rings K are attached the stirrups or foot-rests S at a gointsuch that when the person using the wheel throws his weight onto the stirrups the center of gravity ot his weight is thrown more Aforward than when sitting in the saddle.

In using the wheel the person occupying the seat F takes hold of the handle m, and in pulling thereon not only tends to rotate the large wheel through the pawlO and theleverage bearing gotten through "the saddle-frame E and the trailing-arms L on the small wheels I, which rest on the ground, but also throws a portion of his weight onto thehandle, which throws the center of gravity of his weight as a whole forward of the center of the wheel, thereby making the wheel as a whole move forward. The same result is effected by pushing on the handlesiinat which time the most ot' his weight is thrown onto the stirrups, and, too, through the pawl N, tending to rotate the mmol-wheel I, and, in consequence of its being geared with the large wheel, the large wheel itself.

In steering the weight of the person is thrown to the side of the machine in the direction to which he desires to turn. rlhis will throw more weight onto the small wheel on that side of the machine, thereby causing it to bear harder on the ground and act as a drag to turn the large wheel in the desired direction.

The canvas Y will act as a protection for the person using the wheel from the sun or rain, and prevent t-lie person from being spattered with mud.

I claiml. A velocipede-wheel having two independent and parallel tires, an intermediate circumferential groove, and a rubber tire ar` ranged in the groove between and below the parallel outer tires, substantially as and for the purposes specified.

2. In a veloeipede-wheel, the combination of two independent parallel tires, two inner track-rails concentric with the tires, and wire spokes, to the outer looped ends of which the parallel tires are secu red, substantially as and for the purposes specitied.

3. In vehicles, a hubless annular wheel provided with a track or tracks concentric with the tire or tread of the wheel, in combination with a frame-work provided with rollerbearings suitable to run on said track or tracks, an annular gear-wheel formed in or secured to said tracks, a motor-wheel secured to said frame-work, a hand-lever provided with pawls engaging with and operating the said motorwheel and the said annular gear-wheel, and steadying-arms secured to said supporting frame-work, substantially as described.

t. In a velocipede, the combination, with an annular wheel having an internal track concentric with its tire, of a motor-wheel arranged therein, a saddle pivoted at its forward end to the shaft of the motor-wheel, and a loose ring arranged in the annulus and which supports the back end of the saddle, substantially as and for the purposes specilied.

5. In a velocipede, the combination, with an annular wheel having an internal track concentri e with its tire, of a loose ring arranged in the annulus and provided with wheels, downwardly and backwardly trailing arms secured to the loose ring and provided at their free ends with road-wheels, a motor-Wheel arranged in the annulus, and a saddle pivoted at its Afront end on the shaft of the motorwheel and having its back end supported by the loose ring, substantially as and for the purposes specified.

G. In a velocipede-wheel, the combination of two independent parallel tires, two parallel ICO IZO

In testimony whereof I have aixed my signature, in presence of two witnesses, this 12th 1o day of September, 1890.
